A photo impact printer is a type of printing press that slams itself into a material in order to transfer ink to it. Photo impact printers often have several features including the ability to start and stop the repetition, change the repetition speed, and recalibrate the machine. They are considered highly industrial and can be used to print shapes and text on virtually any material. While photo impact printers are rather reliable and efficient, their supply costs are high and they are high maintenance. As a result, photo impact printers Read More

Video applications often require you to manage several different signal sources. A video multiplexer is a device that helps you put recordings of signals from multiple security cameras on one cassette. It handles several video signals simultaneously. Video multiplexers can split a monitor into various display areas and vice versa, i.e., combine output signals from several cameras to a single monitor. You can then record your combined signal on your VCR or wherever else you want to record. They can also provide simultaneous display and playback features. Some video multiplexers Read More

Lossy compression is a type of compression that removes unnecessary components of a file to reduce the file’s size. Lossy compression is often used in multimedia files, such as still images and audio files that hold a significant amount of redundant information. Lossy compression results in a reduction of quality of the file that is being compressed, but the quality difference is usually not noticed by the human senses. Because of this, multimedia files can be significantly smaller when compressed by lossy compression.   Applications Lossy compression can be used Read More

DVD players, while extremely affordable and for the most part reliable, do become dirty. In almost any environment, dust, pollen, hair and other contaminants can penetrate the DVD machine which can impact the playing of digital media. The good news is that with just a few household tools and occasional maintenance, you can keep your DVD clean and running smoothly. Tools Needed to Clean the Exterior of your DVD Player Most parts of the exterior of the player can be cleaned with simple household products such as: Rubbing alcohol or Read More

A World Wide Name, or WWN, is a 64-bit or 128-bit name assigned to each manufacturer of network storage devices and fiber channels by the Institute of Electrical and Electronics Engineers, or IEEE. Each network storage device that a manufacturer produces must include the manufacturer’s WWN, which is used to identify a network storage device on a Storage Area Network, or SAN.   World Wide Name Vs Mac Address World Wide Names are similar to Mac Addresses, but are formatted differently. While a MAC address is used to identify a Read More

Athlon is a name for AMD’s main line of Intel-compatible CPUs. The Athlon line is designed to complete against the Intel Pentium CPUs. Athlon CPUs feature a L1 cache with 64KB of memory for data and another 64KB of memory for instructions. Athlon CPUs support MMX, 3DNow!, and SSE. Some models of Athlon CPUs also support SSE2. Athlon CPUs are designed to fit Socket-A or Socket-754 CPU sockets. Athlon CPUs are slowly being phased out in favor of the newer Athlon 64 family of CPUs.

A Port Replicator is a device which is used to connect portable computers such as notebook computers or laptops to non-portable peripherals i.e. monitor, keyboard, scanner or a printer. Instead of connecting directly to the notebook computer, the peripherals are connected first to the Port Replicator and the notebook computer is then connected to the Port Replicator. This allows an individual to connect a number of peripherals simultaneously to a single notebook computer. A Port Replicator contains common computer ports such as USB, serial and parallel. It usually contains a Read More

Blu-ray discs have widely replaced CDs and DVDs, though they are based on similar technology. They are superior to CDs and DVDs because they allow the user to store much more information, encode high definition audio and video, and provide support for a wide variety of codecs. Blu-Ray discs also allow users to do everything that they could with a CD or DVD, including reading, writing, and re-writing. The Blu-Ray Disc Association introduced Blu-Ray discs, which over 200 leading consumer electronics companies worldwide currently support. How Blu-Ray Discs Work Blu-Ray Read More

AMD64 is a set of 64-bit extensions to AMD x86-compatible microprocessors. AMD64 extends the industry-standard x86 instruction set architecture while maintaining full compatibility with existing x86 applications. The 64-bit architecture of AMD64 enables applications to utilize up to 256 terabytes of memory, overcoming the 4 gigabytes limitation of 32-bit processors. AMD64 doubles the number of general purpose registers to 16 and doubles their size to 64-bits. AMD64 also doubles the number of 128-bit XMM registers to 16. AMD64 includes support for SSE and SSE2 instructions. Later releases of AMD64 add Read More

An Uninterruptible Power Supply (UPS) is a device connected between the power source and a computer to ensure that electrical flow is not interrupted. UPS devices use batteries to keep the computer running for a period of time after a power failure. It is not to be confused with standby generators which do not provide protection from a momentary power interruption, or which may result in a momentary power interruption when it is switched into service, whether manually or automatically. UPS devices usually provide protection against power surges, brownouts and Read More
